Many robots designed to operate on or in water are destined to serve in military, naval, and homeland security capacities. Others are aimed at scientific exploration and data gathering, such as monitoring marine ecosystems and gathering data about water quality. Some of the plainer ones are remotely operated vehicles (ROVs), underwater unmanned vehicles (UUVs), or autonomous underwater vehicles (AUVs): the naval versions of their unmanned ground vehicle (UGV) and unmanned aerial vehicle (UAV) counterparts. Others look like fish, jellyfish, or submarines.
Whether they navigate the salty seas or fresh water lakes, rivers, or oceans, many models can do a number of different types of tasks, depending on their payloads. Robots made to work in water are usually designed to be either remote-controlled or autonomous, and some can even switch from one mode to another.

The Serpent remotely operated vehicle (ROV) from Seaview Systems is designed for exploring very small-diameter pipelines. It can investigate conduits as small as 9 inches (23 cm) in diameter, and fit around bends with a radius as narrow as 27 inches (68.5 cm). Measuring 9 inch x 9 inch x 57 inch (23 cm x 23 cm x 145 cm) and weighing 70 lb (32 kg), the Serpent runs on two 300W brushless DC motors that give it a total forward thrust of 18 lb (8 kg). With a 0.5 inch (1.3 cm) diameter fiber-optic tether, it can explore as far as 6,000 ft (1,830 m) down a pipe or tunnel. A 360-degree pan/orbit/zoom color camera and two color cameras are included, along with two 70W high-intensity LEDs. The robot also has heading, pitch and roll, and depth sensors, as well as sonar. A fiber-optic telemetry system provides up to three video channels, four RS232 channels, and two RS485 channels. (Source: Seaview Systems)
William, I wasn't sure where your (usually) straightforward statements ended and tongue-in-cheek started, either. Re Google, I know what you mean: it's getting harder and harder to find good basic info instead of commercial/sales info. But that result was predicted when the Internet became commercialized.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
